Description

Screw conveyer

Technical Field

The utility model relates to a screw conveyer technical field, in particular to screw conveyer.

Background

The spiral conveyor is one of important conveying devices indispensable to modern production and logistics transportation, and the spiral conveyor pushes materials by a rotating spiral blade for spiral transportation, so that the force for preventing the materials from rotating together with the spiral conveyor blade is the self weight of the materials and the frictional resistance of a shell of the spiral conveyor to the materials. The spiral blades welded on the rotating shaft of the spiral conveyor can be adjusted according to different conveyed materials. The spiral conveyor has the advantages of simple structure, small cross section size, reliable work, low manufacturing cost, convenient middle charging and discharging, and capability of stirring materials in the conveying process. At present, screw conveyer wide application in all trades, for example trades such as building materials, chemical industry, electric power, metallurgy, coal mine charcoal, grain, current screw conveyer includes the casing and sets up in the casing and both ends stretch out the outer pivot of casing, and in the use, because the leakproofness between pivot and the casing is relatively poor, and then leads to the material to spill over in the gap between pivot and the feed cylinder to the wasting of resources.

SUMMERY OF THE UTILITY MODEL

Not enough to the above-mentioned among the prior art, the utility model provides a screw conveyer, its is rational in infrastructure, and the leakproofness is good, reduces extravagantly.

In order to achieve the above object, the utility model adopts the following technical scheme: screw conveyer, including drive arrangement, casing, front end housing, axis of rotation, helical blade and rear end cap, be equipped with feed inlet and discharge gate, its characterized in that on the casing respectively: the improved shell structure is characterized in that flanges are arranged at two ends of the shell respectively, annular grooves are formed in the side walls of the flanges, the front end cover, the rear end cover and the flanges are fixed through bolts respectively, protrusions matched with the annular grooves are arranged on the side walls of the front end cover and the rear end cover respectively, two uncovered cylinders are sleeved at two ends of the rotating shaft respectively and are arranged oppositely and located inside the shell, and grooves matched with the uncovered cylinders are formed in the side walls of the front end cover and the rear end cover respectively.

As an improvement: the protruding end is provided with a rubber pad, and the width of the rubber pad is larger than the width of the protrusion.

As an improvement: the uncovered cylinder body is welded with the rotating shaft.

Compared with the prior art, the utility model the advantage lies in: utilize protruding and ring channel to cooperate, be equipped with the rubber pad at protruding tip in addition, prevent that the material from flowing from the gap between casing and front end housing and the rear end cap, in addition, be equipped with the uncovered barrel in the axis of rotation, and uncovered barrel cooperatees with the recess, prevent that the material from flowing from the gap between axis of rotation and front end housing and the rear end cap, reduce the loss of material.

Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1, 2, 3 and 4, the screw conveyor includes a driving device 1, a casing 2, a front end cover 3, a rotating shaft 4, a screw blade 5 and a rear end cover 6, the casing 2 is respectively provided with a feed inlet 7 and a discharge outlet 8, two ends of the casing 2 are respectively provided with a flange 9, the side wall of the flange 9 is provided with an annular groove 10, the front end cover 3 and the rear end cover 6 are respectively fixed with the flange 9 through bolts, the side wall is respectively provided with a protrusion 11 matched with the annular groove 10, two ends of the rotating shaft 4 are respectively sleeved with a uncovered cylinder 12, the uncovered cylinder 12 is welded with the rotating shaft 4, the two uncovered cylinders 12 are oppositely arranged, the two uncovered cylinders 12 are both located inside the casing 2, the side walls of the front end cover 3 and the rear end cover 6 are respectively provided with a groove 13 matched with the uncovered cylinder 12, the end of the protrusion 11 is provided with a rubber pad 14, and the width of the rubber pad 14 is greater than the width of the protrusion 11.

The utility model discloses when concrete implementation, uncovered barrel 12 and 4 welding of axis of rotation, put into casing 2 with axis of rotation 4 inside, connect drive arrangement 1, it is fixed with front end housing 3 and rear end housing 16 and casing 2, uncovered barrel 12 inserts recess 13 on front end housing 3 and the rear end housing 6 respectively this moment, when carrying the material, through the blockking of uncovered barrel 12 to the material, the material is difficult to get into in the gap of axis of rotation 4 and end cover from uncovered barrel 12, thereby make sealed effect better.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included within the scope of the present invention.
